` Application May 29,1942, seriarnofnaoca Claims (Circo-95)` This invention relatesto outer doors.` for dwellings or homes, and more particularlyto aconstruction involving duplex orl double` doors, both supported to swing on a single or common` piV-.

otalcenter.` y y A Objects Aof constructions are found in means, devices or attachments for maintaining a main onhouse doorl and an attached screen or other companion door in an 'open position, as a unit, means being also provided for maintaining the screen or other `door in a closed position and the Usual or house door in an open position; and a third position would be shown as with both doors in a closed or locked position. 1 Inventive features of constructon are present in the parts and attachments carriedI by the frame of the screen door, permitting face toface attachment in the normal employment of both doors as a unit. y

Other objects of the invention are to effect simplcity and eiiiciency in such constructions and to provide an extremelysimple constructon which is economical and reliable in operation, and not costly to build. l*

'Still other objects of `the invention will appear as the description proceeds and while herein details of the invention are describedin the specification and somefof the claims, the invention as described in theV broader claims is vnot limited to these, and many and various changes may be made without departing from the scope of the invention as claimed in the broader claims. Normally, the opposed lfaces of the doors are never brought into actual contact, but are maintained in a slightlyseparated position by suitable means, such as rubber buttons mounted on short screw Shanks which `are driven into the material of one or the other of saiddoors, andv this method 'avoids undue nose when the doors are brought into face contact, "the said rubber should the house door 'be blown shut lby a sudden draft.

Other novel elements comprising parts of this structure will hereinafter be pointed out in the following description and then pointed out in the appended claims.

12fillustrates a fragmentary elevation of Referring more particularly to Figs. 1, 2 and 3 of the drawings, the main or house door I3 is supported on three separate hinges (not all shown). One of the said hinges I4 is shown in Figs. 1, 2 and 3 as applied to near the central or lock-rail portion of the door I3, while upper and lower hinges I5 (Fig. 4) may be employed to connect the top and bottom portions of the stiles I6 of the door' I3'to its frame.

The screen or other door I1 comprising a ventilating companion for a non-Ventilating house door comprises many inventive features not heretofore known to the public, and its construction and operation will now be carefully disclosed to those familiar with this art. The screen or other is swung into the room of the dwellingand the screen door is in its locked position, barring entrance to said room. The shutter 4I (Fig. 12), is formed with a lateral arm 43, having a trip-slot 44 to receive a trip pin 45, extending inwardly from a slide bar 46 formed with an upwardly directed push handle 41 screwed to the rear end of a slide bolt 48` f or normally locking the screen door I1. i

The lock bolt 48 may also be pulled back out of operation against the action of springs contained in suitable bores in the rear end of the lock bolt by grasping a thumb piece 49 in Figs. 2 and 3,

. and in Fig. l2 of the drawings the inner lateral door I1, positioned as the outer door of the corn- 4 l said hinges I4, and for preventing the pins I9` from turning in the alined eyes or loops of the main hinge members, we preferably employ set screws for clamping said pins I9 against rotation, as will be understood (see Figure 1 of the drawings). i

In the practice of our invention, it is desirable to impart a closing urge to the outer screen door when said doors are not connected, one to the other, by a spring-actuated interlocking hook or the like, shown at 2I, in Fig. 10 of the drawings, when both doors are swung together to an open position, as in Fig. 5, for entirely freeing the doorway.

The interlocking hook 2I preferably swings downward as shown in dotted lines in the said Fig. 10, when a push button 22 is pressed, to cause a nose 23, to rock the hook 2|, as described, and cause said hook to clear a catch-plate 24, thus disconnecting the combination doors I3 and I1, as will be understood, to permit them to swing independently.

The outer or screen door I1 is preferably mortised at and near the point of connection of its lock-rail 25, with the stiles 26, as indicated in a general manner by the numeral 21.

An elongated channeled face plate 28 is made fast to the outer face of the swinging or free stile 26 of the screen door I1, by screws or pins 29, and said face plate 28, in its indented face portion, is provided with an upper window 30, registering with a key-hole plate 3l (see Fig. 8), through which a key may be passed for unlocking the inner or house door, and a lower windowA tact thereof, and near the lower ends of these.

doors are provided coincident mail slots36 in the house door and at 31 in the screen door, the former having a closing gravity plate 38, while the latter is provided with a springeactuated plate 39 for closing the mail slot from the outside.

The normal or closed position of the interlocked inner and outer correlated doors I3 and I1 is best disclosed in Figure 3 of the drawings, and it is in this position that the inner or house door is locked and the screen door is confined between a vertical bead or shoulder 40 andthe spacing buttons 35. i

Slidable shutters 4I and 42 are employed to close the windows 30 and 32 when the house door arm 43 of the window closing shutters is shown with a follower slot 50, through which a pin or roller 5I travels when the house door I3 swings on its pivot and this roller 5| is carried by the outer lateral arm 52 of the outer window closing shutter 42 (Fig. 13) and this lateral arm 52 is formed with a slot 53 similar to the slot 44 of the opposite shutter 4I (see Fig. 1)

By referring to Figure 1l, we have devised a safety lock for combination doors for preventing inadvertence or carelessness in opening and closing the doors, and for this purpose we employ a short revoluble gear shank 53 with a handle 54 so that when the house door I3 is unlocked and swung open, the gear shank is rotated about half a revolution by an operator, thus sliding a bolt 55 to the right and into its socket 56 for locking the screen door and for projecting an upper bolt 51 outwardly for presenting its beveled face 58 in the path of the house door I3, should it be closed by a draft of air, and thus the house vdoor snap-bolt will automatically re-lock itself for safety, and the screen door bolt will again be withdrawn from a locked position, as lwill be understood.

Referring to Fig. 15 of the drawings, the upper end of each pintle I8 is formed with a kerf or cross-cut 59, into which is turned the upper` terminals 60 of torsion springs 6I terminating at their lower ends in torsion exerting arms 62, for urging, through hinge plates 63, the screen or outer door I1 constantly to a closed position against the stops or shoulders 40, best. shown in Figs. 2 and 3 of the drawings. l

The spring terminals 60 are set or locked in the bottoms of the kerfs 59 by clamp screws 64, which enter through central holes through 'the topsy of said thimbles 65, as shown in Fig. 15 of the drawings and by the above construction, the screen or other door I1 may swing independently of the house door I3, when said doors are not interconnected, as will be understood.

The door hinges I4, I5 at the lock-rail and at the top and bottom of the companion doors lI3 and I1 are somewhat similar except that the attaching plate 66 for the screen door at the lock rail 25 is provided with inside grooves 61, for receiving a pull-chain 68, controlling the stretch of parallel springs 69, for at all times holding the chain 68 taut around the swinging outer corner4 lil of the house door, as clearly shown in Figs. 2 and 3 of the drawings, and this position of the parts acts to urge the house door I3 around and inward on its pivot. When closing the house door the chain which is in engagement with the innerA 12, as in Fig. 11, or in any other approvedrmanner.,

Guide bars 13 are riveted to a rear plate 14, and said plate is secured to the said lock rail of the screen door by screws or pins 15 best shown in Fig. 1, and these bars 13 serve to guide the lateral arms 43 and 52 of the window closing plates or gates 4| and 42.

The pull chain 68 operates through a metal tube I6 for the greater part of its length for guiding said chain and for assuring proper direction.` As shown in Fig. 1, an auxiliary bolt 11 operable from inside the house by a handle 18 may be employed.

We claim:

`1. In combination, a house door for dwellings, a companion door mounted to operate through a single'frame with said house door, said doors being connected as a unit, a knob on said house door, an open frame on said companion door adapted to receive the knob when said doors are joined as a unit, a shutter adapted to cover and uncover said open frame, and means adapted to uncover said opening on the approach of said house door.

2. The combination of claim 1, in which the power for opening said shutter is derived from the closing movement of said house door.
